The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

The blinks and flickers referred to here can best be described as “voltage fluctuations on electric power systems [that] sometimes give rise to noticeable illumination changes from lighting equipment.” The Institute of Electrical and Electronics Engineers (IEEE) standard that covers this is about to

LED lighting can be powered and controlled through a PoE system in a data center application.

Power over Ethernet (PoE) is any of several standardized or ad-hoc systems that pass electrical power along with data on Ethernet cabling.

The 2010 edition of NFPA 72, National Fire Alarm and Signaling Code, established a new and separate chapter for emergency communication systems (ECS), which continues to evolve.

In its basic form, commissioning means testing every device, process and procedure in an integrated systems solution to ensure the final specification operates as planned and according to the owner’s design.
